           Summary: dmd: cannot execute: Permission denied
           Product: D
           Version: D2
          Hardware: x86_64

            Status: NEW

          Priority: P1
         Component: dmd

DMD does not have execute permission after installation via make install. It is therefore necessary to manually give execute permission to the dmd binary.

Output log:
./dmd -v
bash: ./dmd: Permesso negato
